To reduce the size of the component store directory, you can decide to make the service pack installation permanent and reclaim used space from the service pack files. However, if you make the service pack installation permanent, the service pack is not removable.
To remove the service pack files from a Windows installation, use the following in-box utilities:
- Windows Vista Service Pack 1 installed: VSP1CLN.EXE
- Windows Vista Service Pack 2 or Windows Server 2008 Service Pack 2 installed: Compcln.exe
- Windows 7 Service Pack 1 or Windows Server 2008 R2 Service Pack 1 installed: DISM /online /Cleanup-Image /SpSuperseded or Disk Cleanup Wizard (cleanmgr.exe)DISM.exe /online /Cleanup-Image /spsuperseded
